It is a Protein Shake for Breakfast and lunch. The Protein Drink must have at least 15 grams of Protein per serving. For dinner a salad with lite dressing fat free, vinaigrette or vinegar and oil. Drink another protein shake at night if needed and one metmucil tablet per day if needed. Until the day before sx. Then its a clear diet. I dont know how to attach things from my phone but I can email you the info from the dr. Or someone can tell me how to.hope this helps. :-)
